Size of Set Screw

The handle of my faucet is very loose. I have either model 9159T-DST or 9959T-DST. I can't tell the difference. I am trying to tighten the set screw but because of very limited space I can not see what size the set screw is. I do not have the original allen wrench that came with the product. Can you tell me what size screw or wrench to use? Thanks.

Hi RKJ,
Thank you for your question!
In order to tighten the set screw on either the 9159-DST or 9959-DST you will need you use a 1/8&quot; allen wrench.
Best Regards,
Daniel

How do you remove the cap to get to the screw?

Hello Lawrence,
Thank you for your question. The button cover RP64072 can be removed by using your finger nail, a sharp pin or finger nail file, in the seam to pop it off.
Best regards,
